[rispoli_23]

LAST NIGHT I TOOK MY TPS SENSOR OFF TO CHECK IT PUT IT BACK ON STARTED IT THE CAR KNOCKED LIKE CRAZY (WTH) SO I SHUT IT OFF TOOK IT BACK OFF AND BACK ON AND THE KNOCK SLOWY WENT AWAY WEIRD RIGHT >>>> THEN I DROVE IT THIS MORNING TO WORK AND CEL P0122 AND P1125 CAME ON AND CAR STARTED JERKING AND STARTED DIEING AND LOST ALL POWER .. I MADE IT WORK FINALLY AND CHECKED THE CODES AND I CHECKED TO MAKE SURE THE CONNECTOR WAS TIGHT AND IT IS ... DO I NEED A NEW TPS ?? IT WAS FINE DEFORE I TOUCHED IT AND ITS A 99 STANG GT SO ITS NOT ADJUSTABLE

holy caps lock batman!

i do believe you car hates you

 

[rispoli_23]

dude i swear my car is cursed lol , i never had an issue with it until i put my cams in kinda makes me wish i did a blower instead haha ... i put a new tps sensor on it and now it runs fine i gues i messed the old one up somehow when i took it off ... my tuner is getting next week and degreeing the cams so ill keep u guys posted ..

Check fuses, inspect connectors

Start by checking all of your fuses. Esp fuse F2.8.

Next inspect the closely inspect the connector. Look for loose/bent pins. Broken/chaffed wires at the connector. It is most likely to be related to the recent work done.

off subject how do u get ur mods and stuff to show up at the bottom of your post

 

[rispoli_23]

nevermind got it sorry

 

[Night Shifter]

dont feel bad..even after i got my car tuned mine stalls like a mofuga...all the damn time..annoying as hell

 

[csledd]

my TPS randomly broke once too. Put on an Accufab TB and plenum and drove 3 hours to get a tune, after one run on the dyno the TPS died. We put a new one on and things were going again, it was quite strange.

 

[rispoli_23]

Nightshifter now u tell me ur car dies ughhh this whole time I thought my car was cursed ... hopefully It gets better after the cams get degreed .... are urs degreed.
. And the tps that broke was like a year old ... damn sensors

 

[Night Shifter]

lol sorry in the delayed info man. maybe i too need a new tps. yeah, my cams are degreed..

weirdest thing, i was throwing 02 sensor codes for both front 02's...had been for a while.. but this time my car was stumbling like crazy at low rpms and just being annoying as hell..it would stall, but very seldomly.. sometimes it wouldnt stall for a few days and some times when it stalled it would take me forever to turn back on..

then, i put new 02 sensors in, and the car drove smooth as smooth could be and it really woke the car back up. BUT, ever since i put the new 02 sensors in my car dies ALL the time now....with the old sensors it would idle sometimes, but with the new ones, yeah forget about idling at all lol...most mornings on the way to work it dies in the driveway and at least twice out on the road unless i keep it in the throttle at idle... i even had it tuned after the new 02's and it still sucks lol

maybe we both need new tps's....but dont feel alone on this one, my car hates me too..

 

[rispoli_23]

that is exactly how my car acts ..... i will say sine the new tps sensor it has not died (knock on wood) ....

 

[Night Shifter]

my car isnt throwing any codes or anything so i have no idea what my problem is lol

did your knocking finally go away for good? im gonna try the new tps sensor as well...id love to never stall again. when did you replace the tps on yours?

 

[rispoli_23]

he knocking went away the next morning and has not came back .. the only thing i can think of is it has something to do with the tps being bad ... i put the new tps sensor on sat morning and reset my idle so far so good .... and trust me i know how frustrating it is having idle issues

 

[rispoli_23]

well damn it started dying again ughhhh... im so fed up ... i wish someone had these issues and new exactly how to fix it

 

[wmburns]

Do you have an ODB2 scanner? If so, monitor the TP-MODE PID. What you are looking for is the closed throttle setting (C/T) when the throttle is actually closed. For a MAF application, the TPS is not used the same way as for a speed density tune.

I suspect your problem is not with the TPS.

Next monitor the air flow, LTFT, STFT, IAC duty cycle, TPS, RPM, and load.

If I were to guess, your problem is with the MAF.

 

[Night Shifter]

are there times when your car dies that it takes like 7 times to crank over?

mines getting worse...i used to die occasionally and now its every time i stop..i know your frustration...sorry i cant help though

 

[Night Shifter]

maybe i might try this MAF idea..only problem is the MAF i can get my hands on is 86mm..really, do i need one that big? doubt it..

*EDIT* haha thats what she said...sorry, couldnt help myself...

 

[rispoli_23]

Yes I can look at all that stuff but I don't know what numbers they should be. .. and yeah bro sometimes it takes a few times before it starts I swear I'm fed up I have spent so much money and my damn car don't run right

 

[rispoli_23]

Oh and Thanks for The help. .. I Can only use my sct and I don't see a pid for closed throttle I know I can see the rpms the fuel trims and the iac duty cycle

 

[rispoli_23]

Oh and load and I think tp voltage. ..
